The code on the back of a timing belt is the fastest way to identify a replacement. On this belt the marking reads 25 / 8M 3600 AFX: the profile is HTD 8M, the pitch is 8 mm and the length is 3600 mm. If your old belt carries the same marking, you have a direct match to the Optibelt Alpha Flex timing belt we carry.
When the old marking is worn or unreadable, check the drive instead. Count the teeth if you can, measure the pitch and the overall length, and note the belt width. Send those details along with your part number, and our team will help confirm the right timing belt or suggest an equivalent.
Timing belts are often replaced as part of a drive service, so inspect the pulleys and the rest of the drive at the same time. If a drive uses more than one belt, replace them as a set to keep the load even. For a quote, send the full belt code, the quantity you need and any photos of the old marking by WhatsApp or email.
